Application filed May 25, 1921. senain'o. 4923151 hogaand State of Ohio, have invented; ceri tain new and useful I mprovements in Combined' High 7 and Low Level Valves and Depth Indicators, of which I hereby declare the following to be a full, clear, and exact.

description, such as ,will enable others skilled in the artfto which it appertains to make and use the same. a

The objects of 'the -invention are to providejan improvement ,in a conibined high andlow lejvel, valve and level indicating device for the gasoline supply leading-'tothe carburetor of an explosionfengine such as is employed to,drive a motor car, and the invention is. designed to notify the operator of the car when the supply 'is' getting low in plenty of time; tozjenable him to call at a gasstation and get the supply renewed.

The device is also constructed and arranged tov provide a -;gaugez.by means of which the levelof the fuel i'rithe main supply tank, can 7 always be ascertained.

The invention comprises, an independent vertical cylinder Supplied with fuel oil from the main supply tank, andcommunicating therewith, and provided w'ith an inlet opening at the lower. ,end, *eonnected by means of a supply pipe or passage with the lower end of said tank, the aforesaid openings in the cylinder and tank being at the same level, said cylinder provided with two outlet openings at different levels, and with a float valve which normally closes the lower outlet, and remains closed until the flow of fuel ceases from the upper outlet, at which time the float valve is manually liberated to permit the fuel oil to flow through the lower opening.

The level of the fuel oil will then be high enough in the main tank to provide a sufficient amount of fuel, to run the motor car to the nearest town, or gasoline station, and, the remaining supply may consist of one or more gallons as desired.

' The invention is hereinafter further described, shown in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings Fig. l, is a vertical section showing the construction of the various parts.

In this view A, is a vertical cylinder through'whichthe supply of fuel 'oil passes from the main supply tank 13, to the carburet'or C, is the supply pipe leading from the lower end of the main supply tank to the lower part of the vertical cylinder A.

The'pipe maybe flexible if desired;

D, is the lower outlet opening leading from the auxiliary container "at the same level as that of the supply pipe C.

Thls opening is normally closed by the float valve, E, which is provided with an elongated stem F, that the movable cover G. i

A cap H", pre's'sed upon'ja taperedseat I, retains thevalve E,'in position to close the protrudes through lower outlet openingD. J, isflasecond outlet opening positioned at a'higher level than theopening D. I 7 I The gasoline 'flows through this opening until the supply thereof is exhausted in the main and auxiliary containers to the lever -of the lower edge of this'opening, At this time a predetermined amount of gasoline will remain in the containers sufficient to enableothe operator to run the car a number of m les, orsufiicient to enable him to reach a g3iSOl1I leSt9Qt1OI1.

The cap. is then 're'movedfr omthe valve stem andgth'e' float will rise thus permitting the gasoline to flow from the lower-opening, D, until the containers are completely exhausted. i

The level of the fuel oil will always remain the same in the cylinder and the container, and when it is desired to ascertain the level of the fuel oil in the main container, the cap is removed from the valve stem, which liberates the float, the elevation of the float can then be easily read upon the valve stem which is preferably graduated for this purpose, this will indicate the level of the fuel oil and the amount remaining in the main container.

The valve stem is preferably constructed of spring wire and a yielding part K, therein, makes it possible for the valve to adjustitself closely to its seat and also provides for a resilient pressure upon the valve, which is preferably composed of cork or soft substance.

The device is most conveniently placed in front of the seat S, underneath which the tank B, is ordinarily concealed as in the Ford motor car, but may be placed in other End should be so set that the inlet opening in the cylinder and the outlet opening in the tank should have the same level.

It also serves-as a means-for attaching'the cylinder to the floor.

Having described the invention what I claim as newand desire'to secure by Letters Patent is:

1. In a combined high and lowlevel valve,

and depth indicator, in combination witha main fuel oil container, and a vertical cyl- -inder supplied therefrom and closed at the bottom, the lower ends of said container and a cylinder being in communication witheach other, saidv cylinder provided with upperand lower outlet openings, a float valve for said lower opening, and releasable means for securing said valve in place, said, valve when released permitting the flow of fuel oil through said lower outlet opening, saidvalve provided with a valve stem, a cover for said cylinder, said cover provided with an opening through which said valve stem is adapted to project when said valve is released, said valve stem comprising a depth gauge, to indicate the fuel ,oil levelin the .main fuel oil container. V

2. In a device for the purpose set forth, 7

in combination with a main container, a vertical cyllnder havlng a closed bottom, a

passage connecting the lower endsof said main container and vertical cylinder, outlet passages leading from said vertical cylinder,

at different levels, a float valve and stem '7 therefor, said float valve adapted toclose 7 'said" lower outlet opening, a closure for the upper end of said cylinder, said closure provided with an opening, a stem for saidyalve, said stem passing through said ope'mng in valve stem and close said valve on its seat whennsald cover ls-put in place over said opening.

8. In a device for the purpose set forth, I

in combination, a vertical cylinder, an inlet opening adjacent tothe lower' end thereof, 7

outlet openings arranged'at diflerent levels leadlng from saidcyllnder, a float valve controlling said lower outer openlng, and a retainlng means for sa d valvesaid retalnmg der.

4. In a device the purpose set'forth if the combination with a main fueloilcontainer, and 'a vertical cylinder supplied therefrom and closed at the bottom, the

said closure, and a removable cover for said i 'openlng, said cover adaptedto engage said means vertically movable on said cylin- 7 lower ends of saidcontainer and cylinder being in communication with each other,

said cylinder being provided with a central outlet opening, and with an outlet opening in its side wall above said central opening," a valve for controlling said central-opening, V. v a cover for said cylinder, said'cover provided with a central opening, a valve stem for said valve, guided in saidcentral opening, and a vertically adjustable cover for 1 said opening, sald cover serving as a reta n-J ingmeans for said valve;

In testimony whereof, I'her'euntoset my hand this 21-day of May, 1921.
